Letters Patent No. 93,587, dated August 10, 1869.

To'cll whom it maycon-ccrn Be it known that I, E. BLUNT, J r., of' the city and 7 county of New York, State of NewYork, have invented certain new and useful Improvements in Ooffee-Pots; and I do hereby declare that the following is a full and exact description thereof.

My invention relates to the top of 'the cofiee-pot, and may be called an improvement in coffee-pot covers. In other words, I propose tovmake covers embracing all the novel parts, which may he sold as sep- I will firstdescribe what I consider the best means of carrying out my invention, and will afterward designate the points which I believe to be new.

The accompanying drawings form apart of this specification.

Figure l is a central vertical section of the entireapparatus, and

Figure 2 is a plan view.

Similar letters of reference indicate like parts in both the drawings.

A is the main body of what would form an ordinary cover, and

d a is the ordinary rim, which extends down near the edge thereof, to fit within the top oft-he coffee-pot.

The body of the coffee-pot, indicated in dotted lines in fig. 1,111 y be of any approved'form and material.

B a plate of tin, iron, or other. suitable -1naterial, mounted a little above the ordinary cover A, and supported in place by the sides 0 of a cold-water vessel or reservoir, 0, which is thereby formed.

The sides 0, below the bottom B, are perforated, as indicated by 1), allowing acirculation of tl1e-atmospheric air from the exterior between the plates A and .B.

D is a conical tube, which joins the platesA and B.

' It is open at both ends, as represented, and is adapted to be tightly stopped by a conical plug, E, which may be of soft metalor other suitablg n'iaterial.

From the plug E, a wire, e,'extends upward through the top cover G of the cold-water reservoir 0..

When the coffee-pot is to be used, the coffee and a quantity of water being placed in the main body of the coffee-pot, cold water is poured into the reservoir 0,

:and it is retained there until the coffee boils, after which the plug E is lifted, by means of the connecting-wire'e, and the cold water is allowed to descend into the coifee-pot through the tube D, performing its well-known function of clarifying or settling the coffee. H is a tube, fixed into the cover-plate A, outside the casing C; It is provided with a whistle at the upper end, as is indicated .by I, and is open at both ends.

So long as the contents of the cofiee-pot are below the boiling-temperature, my coffee-pot serves simply in its ordinary manner. When the cofi'ee boils, the steam passes out through the tube H and whistle I, and produces a loud sound, which attracts the atteu: tion of the attendant, and thus aids to insure that the. vessel will be removed from the fire, and the plug E lifted, about the proper time to avoid'too much cooking the coffee. 1 I

In all previous attempts to introduce whistles or self-acting alarms for this purpose, the whistles have been placed in or connected to the They were either liable greatly in the way.

- In supplying either the water or the cofiee, some was liable to be received in the whistles, and in case cold-water vessel. to become choked or to be the eofifee boiled violently, the whistles were again liable to be obstructed. In by forming a part of the the means of communication: between the same and the interior of the c'ofiee-pot, introduced such objectionable features as to prevent their general adoption.

My improved arrangementallows a free and direct communication from the interior of the cofi'ee-pot to the external atmosphere through the-whistle, preserves the whistle from choking with water or-with coffee,=

other words, the whistles,

and allows both sides of the whistle to be easily in-" 'spected and cleaned when required.

I do not claim, broadly, awhistle, in connection with a coffee-pot, to give an alarm when the boiling commences, as such have been often proposed,.and is also described in a patent to me, dated N ovember3, 1868; but all previous whistles on cofi'eepots have been so arranged in reference to the other parts, that both sides are not accessible, and they are liable to become choked and deranged, while mine, by its improved arrange ment, is, in a great degree, free from all liability to derangement.

Having now fully described my invention,

'What I- claim as new incofi'ee-pots, and desire to secure by Letters Patent, is-

The within-described new combination and arrangement, to wit, the cold-waterv vessel 0, with the conical.

plug E e, for letting down itscontents at will, and the whistle I, mounted outside on the independent tube H, all substantially as and for the purposes herein set forth.
